nrPAnATus non DISPLAY.

Application led February 21, 19.23. Serial No. 620,352.

To all whom t may concern.'

Be it known that ROBERT L. ANTHONY, a citizen ofthe United States, residing at Providence, in the city and county of Providence and State of Rhode Island, has invented new and useful Improvements in Apparatus for Display, of which the following is a specification.

This invention relates to an apparatus for display, and more particularly to an apparatus adapted for educational and advertising purposes.

It is particularly useful in that it provides a convenient way toinstruct or convoy information with respect to the steps carried out in a manufacturing` process, or in the operation of a complicated machine. It is well known that an individual is likely to be more interested in purchasing an article when he. is familiar with its mode of operation or the process of manufacture whereby it acquires its superior land distinctive qualities. The general public is frequently unfamiliar with manufacturing processes 'and the operation of machines, not so much on account of disinterestedness, as

- on account of the effort necessary in obtaining this information and inability to obtain access to the factories for observation of processes.

It is an object of my invention 'tolr provide an apparatus for instructing` the general public and arousing their interest in av manufacturing process or machine and I do this by providing an apparatus for displaying the particular process or` machine in a complete, satisfactory and novel manner,

and so that, in a few moments of observation, a large number of people may obtain substantially complete birds-eye view of the process or machine. My invention is suitable for use in educating and instructing one relative to many kinds of manufacturing processes, the operation of machines, the

eases, etc.

In this application I have disclosed a unitary apparatus for disseminating information relative to the mamifacture of cotton cloth. It has been found very useful as an advertising device for installation in show windows, at exhibitions, etc.

dis-

Another object of the invention is to provide an apparatus for display which delineates the carrying out of a manufacturing process from raw material to finished product and which displays the product at various stages of manufacture with an ap-l propriate legend descriptive of the product,

` and preferably with an illustration of the machinery used at a corresponding stage maiuifacture.V y Y Another 'object of the invention is to provide a display apparatus in which the carrying out of a manufacturing processor the operations of a machine may be demonstrated to an observer,l the observer being shown a physical embodiment of the lnediuni at eachstage or step, together with an illustration appropriate to the medium displayed.

Another object of the` invention is to provide a display device which may be operated by suitable power, such as an electric motor, to successively bring into View samples showing the condition of the product at the various stages of manufacture, and tosiimultaneously control the observability of a suitable image, such as a picture or transparency. f l v v y Another object of the invention is to associate with a continuously moving motor driven mechanism. a series of'display ele--` ments each carrying some article to be displayed, together with suitable contacts for controlling the electric circuit of a lamp for illuminating a picture appropriate to the article displayed, and preferably to arrange the display elements so that one is brought into view and a corresponding lamp lighted at about thel same time as 'the preceding one 1s taken out of View and the corresponding lamp extinguished.

Another object of the invention is toiprovide a unitary display device `by which the manufacturer can show his factory and his `manufacturing process, the latter both by a physical exhibit and an' appropriate illustration, in order that the entire exhibit may be easily moved from one store window to anotherv and from one town to another without dismantling. Y Y

For purposes of illustrating the invention,

f I have shown the carryingout ofthe disthe fibre.

play in connect-ion with the. manufacture oit cotton cloth, which may be considered as starting with the bales oic cotton. These bales weigh approximately five hundred pounds, and are made up of cotton bolls from which the seeds and some of the foreign matter have been removed by the cotton gin. The fibres in the bale vof cotton are in no particular order. Instead, they are extremely tangled. The manufacturing of cotton clothmay be, to a large extent, considered the process of straightening out these fibres and spinning them into threads, then weaving the` threads into cloth. lt is the story of such a process that this embodiment is to showl tol the. observer.

The lirst step after removal of the bu-rlap from the. bales of cotton is that of cleaning T he cotton fibre is fed into openers where it is milled around until the matte-d masses are'loosened and the cotton isl in shape to be conveyed to the machines called breaker pickers. ln these pickers, arms striking the stream of incoming fibres very rapidly pound out bits orf dirt, leaves,-sand, motes, and foreign particles. The cotton is then in large sheets similar to. cotton batting and is wound on cylinder-sto produce a'lap. Two or more of these laps are then brought together and run through a doubling machine which mixestogether the cotton libre from a plurality ogf bales of cotton.

These laps, which resemble huge rolls of absorbent cotton, are taken Vfrom the picker to the carding room. In the cards are drums operating at different speeds. These drums have steel teeth which comb the cot-V ton, and the cotton comes from the cards in a fleecy sheet, as light as a cobweb., It is then'drawn through a funnel into anuntwisted rope, or sliver. These slivers are then doubled and passed between rollers which stretch them out to several times their original lengthwhereupon they are assed to a slubber which winds the fragilev eottonyarn for the first time upon a spindle and gives it an initialtwist. More doubling. more stretching, more twisting, and more winding are given to thecotton in what are called roving machines which prepare the fibre for the spinning` operationwhereupon itreceives a final twist to make it into yarn.

rlhe yarnwhich is intended for the filling goes direct from the spinning machines, while that which is intended fork thev warp is prepared to stand a heavier stra-,in in the weaving process. lt is spooled, then the threads are taken from the spools and rewound in parallell form on a warp beam. r.Che warp yarn is then slashed by being.

is carried out in the loom in which the warp yarns are alternately raised and lowered by a harness. The shuttle carries a strand of iilling -yarn first under and then over a thread of warp yarn, thus weaving in the. strand. The strand is then pushed into the cloth. The warp is unwound from the loom beam automatically at the proper speed just as the cloth is taken up and wound automatically into large rolls after it has been manufactured.V The cloth from the loom then passes through a brushing machine, is inspected todetect flaws and insure a uniform quality andl is then folded or rolled.V

The cloth is then known as gray goods and is in condition for converting or finishing. The v unbleached cloth is yellowish gray 1nl appearance and contains impurities which were not removed during the spin` ning and weaving. It has also picked up additional impurities in the mill, and fuzzy ends of libres are sticking to the surface. These are removed by si'ngeing and shearing.

For certain purposes it is desirable to have white cloth and it is then necessary to. bleach the goods. This is carried out by chemical means and the white cloth is delivered from .the bleaching process. For many purposes, however, it is desirable that the bleached cloth be printed or dyed, in orderl that attractive and permanent colors and designs be available. Either of these operations is carried out in suitable machinery. 'The bleached cloth or the printed or dyedy cloth is then prepared for the market by being finished, which includes starching, tentering, calendering, mercerizing, etc. .The finishing gives the cloth the desired feel, the required uniformity and the particular degree of smoothness essential.

The drawings show a layout of an embodiment of this invention suitable. for displayingthe process which has just been described. ln these drawings:

ln order to carry out the illusion that the observer is looking at a cotton mill, the illustrated device may be designed to resemble in appearance suchv a mill, a front view of which is shown in Fig. 1. Arrailroad siding is `shown at the left, ,this siding being adapted to carry a car to illustrate the bringing in of the baled cotton. At thel right is shown another railroad track 11 which illustrates the shipping platform from which the finished goods are sent away from the mill.

In this embodiment of the invention, the

representation of the wall of the mill is divided into a number of sections. V'Ihese sections4 are utilized to carry out the displaying of the process. A convenient way of doing this is to divide the lower portion of the wall into a number of sections 12, which are carried on rotatable platforms or scene-Shifters 13. A legend, which may be either in the form of a` transparency or merely a printed sign, is placed above the sections 12. This legend is preferably a short description of the stage of the process which it is desired to illustrate in the corresponding section of the wall.l Above the legend 14 there may `be placed a comparatively large transparency 15 which when illuminated will illustrate the machines used at this stage. The exhibit is provided with a suliicient number of sections, legends,

and transparencies to properly display the process for which the device is designed.

In the device illustrated in Fig. l eightv of these sect-ions are shown and when arranged for displaying the manufacturing of cotton cloth they may be conveniently arrangedto show, first, the picking opera'- tion in which the cotton is opened, cleaned and put into lap form; second, the carding operation in which the libres lare cleaned and brought parallel; third, the roving in which the ends are brought down and twisted; fourth, the spinning in which yarn is produced; lifth, the warping in which the 'yarn is brought in position for weaving; sixth, the weaving in which the filling and warp are combined; seventh, the inspecting; and eighth, the bleaching to make the cloth white.

I will now describe the details of a mechanism which I have found suitable for carrying out the display contemplated. Fig. 2 which is a section taken onthe line 22 of Fig. 1, shows the general layout of this mechanism.

An electric motor is provided with suitable rreduction gearing 21 to drive a sprocket wheel 22 which may be conveniently located adjacentone of the sections 12. This sprocket wheel in turn drives Artf-'chain 23 in the direction indicated by the arrow the chain passing about a spring-controlled tightener 24 and about a sprocket wheel 25 preferably located ad]acent the other end Vsection l2. The chain 23 is provided with a plurality of lugs 26, two ofk which are shown in the drawings. The portion 27 of the chain, which lies between the sprocket wheels 22 and 25, is carried directly backL of the front wall 28 of the mill and mayconveniently be located underneath theV Hoor level. The sections l2 of the walls 28 are carried on turntables or scene-Shifters 13 mounted kto turn on vertical axes 29.

These turntables 13 vare associated Vwith driving mechanism, illustrated-more in detail in Figs. 4 and 5, whereby they may be driven from the sprocket chain 23 by means of the spaced apa-rt lugs 26 attached. to the chain. The lugs 26 are carried underneath agear 30 and engage with one of a number of spaced apart pins 31, which are rshown more clearly in Fig. 5. The movement of the lugs will turn the gear 30 part way around on its axis and this in turn will rotate a smaller gear 32, carried bythe spindle 29, a half revolution; thereby turning' the turntable halfeway around each time one of the lugsv26 engages-the pin 31. In order that thefturntable may be stopped in the desired position, without overrun ning or turning backwards, there is provided a yielding leaf spring 33 mounted on a support 34, sothat the spring is adapted to engage two of the pins '31. t t

, These turntables 13 may be conveniently made upvof a thin discpof vsheet instal, carrying an upiright element 35 on one vside of which one may conveniently place the representation of the lower portion of the walls ofthe mill which the display isto represent. In Fig. l this upright 35 is shown as having windows and bricks outlined thereon.v The opposite or inside wall of the upright 35, together with the back portion 13a of thev turntable disc are utilized as a support to carry a suitable `physical "embodiment of the 4product or medium for which the device is being used.

In order to properly :illuminate the legend 14 and transparency 15 appropriate for the particular display being carriedon one oi" the scene-shifter devices, theV lower surface of the Vdisc 13 is provided 'with a strip of insulation 36 on which is supported an contact plateV 37 adapted to engage at the4 propertime a pair of the spaced apart contacts 38 and 39 in a lighting circuit. These` contacts are supported on a block of infor the building. This framework may in- Lsulation 40, carried on a part ofthe frain-k clude a front sill 43, a rear sill 44, suitableV cross members 45 connecting the sills 43 and 44 and fastened to theV channels 41 and 42. The frameis also provided ivi-th suitable uprights, designated 46,k adapted to. support the upper part of the exhibit. The arrangement of these uprights will vary according to the type of mill, which it is desired to show. The sprocket gears 22 and 25 and the members 26 are preferably supported direct from. the channel member 41?, While the turntables 13, driving gears 30 and contact insiilating strips are carried by' the other channel member 42.V This arrangement of framework aiiords a light-Weight structure vwhich is suiiiciently rigidv forv the purpose and which can be'easily transported.

At they left in Fig. 2a, an additional sprocket gear isshoxvn as` being mounted on. the shaft-fof the sprocket wheel 25. The gear 50 is adapted to drive through a sprocket' chain 51 and a Vsprocket Wheel 52, connected With a larger sprocket Wheel53', a chain 54. This chain 54 passes about a smallidler 55 carried in theback part of the exhibit and about a third gear 56. The gea-rs 52, 53, and 56 are preferably mounted in the end portion of the channel member. This chain lcarries a miniature car 57 in 1 such aposition that it `apparently travels through a slot 6.1 and, in the operation of the device, brings theI car out of the` opening 62' in the front of the exhibit and' carries it `inthrough the openingY 63 to make it appear as if the carlioad otlbaled cotton were beingbrought intoA the mill.

A sprocket gear 65. is carried underneath the sprocket gear 62 and this drives through a sprocket 65 and gears 6.6 and 67, a sprocket chain 68 passing about gears 69 and 70. The chain 68 carries a. car: 71v in a manner similar to the Way the car 57 is carried by the chain 55, and this car is, at the proper tin-ie, brought out by the chain 68 through an opening 72 in the Wall of the representation of the mill,'the car is then carried along in front of the observerandthrough an opening 73 to illustra-te the shipping of the hnished goods and,.it desired, their receipt by the. customer. LThegears 66, 67, and 69 are carried on the right handend portion .oi the channel member 41.

The circuit diagram for the device herein illustrated is shoivn in AFig. 7. The power is taken from the mai-ns through a control switch 81 to operate the vmotor 20 and thence -tothe lighting circuit of the display device. This lighting circuit has one wire 82 Whichis connected directly to the lamps. The Vother Wire 83 isk connected directly to such of the lamps as are intended :tor general or continuous illumination, and is connected to the contacts 39 carried underneath the tables 1 3. The contacts. 38 are connected to the other side of lamps 84, 85, 86, 87, 88, S9, and 91. Y

Each odi these lamps are in compartments Fig.. 3 showslamp 84 in a compartment 92 inside the representation of the cotton` mill and above the i'irst turntable. In this ligure the turntable is shown as being turned to display article 93, and the contact 37 moved around into. the position to connect with,L the contacts 38 and 39. The Vtransparency 15 andl the legend 14 are at the vliront oi the compartn'ient 92, hence, it is apparent that Whenever the turntable is turned to the position of Fig. 3,` to sho'iv the articlecarried thereby,A then the` lamp S4 is lighted, thereby illuminating the transparency so that the observer may read the Y legendand may observe the brightly lighted view having an appropriate illustration.

lnv the embodiment herein illustrated, vthe factory isshoivn as vhaving .tivo towers and 101 provided with Winde-Ws 102. In oider to render the exhibit inoie attractive these towershave been illuminated by means of lamps 104 and 105.` connected directly across the lightingmeans 82 and' S3. The exhibit is also vprovided. with transparencies 106; and. 107 arranged to be illuminated by lamps 108. and 109. @ne of these transparencies is placed at either end of the eX- hibit andthey carry an. appropriate picture.

Here the left picture shows the field of cotton, While the one at the right might show. the printing operation which is carried outY oni thefinished goods, oran interior ofa. department store.

The-subject matterof the exhibit may be describedin a general way by a. sign suoli as is shown at 110 illuminated byl lamps 111. This sign is preferably so arranged that it can be read at much greater distance than. i-s.possible iviththe smaller legends.

The cycleof operations carried out by the presen-t embodiment olthe device is as follows; The car 57 is first seen coming out through the opening 62 at the left end ofthe `display apparatus.. The car then passes tothe righ-t along the track or siding 10 andenters into the mill., as shown atthe .left hand endY of Fig. 2a. The `car carries a suitable legend and may, to further carry out the illusion, be in they form oit a box car With an open door and filled with little bales of. cotton. Just as the car 57 .enters the mill, the" .mechanism is preferably ,soI timed tliata lug 26 in a chain 28 enga-ges. one of the pins ,'31 so that the gear 30 underneath the left handturntable 13 is moved. AAs the chainmoves along the gears 30 and 32 are rotated to sufficient extent to turn the turntable from the posiist tion wherein the object was concealed, to a position to show the object. The leaf spring 33 cooperating Withthe pins 3l serves toy insure that the turntable is stopped at eX- actly the right place. in this position the contact 37 bridges the contacts 38 and 39, thereby illuminating the lamp 84. This lamp, in turn, Vbrightly lights the transparency and the observers can, in the embodiment under consideration, non7 see a small roll of cotton which is passed through the picking machines. They also see a detailed illustration of these machines and --read the` small appropriate legend. Vhere the device is Vused for show Windou7 dem onstratioii, it may be made of such size lthat `very accurate illustrations of the machines vmay be shown inthe transparencies, or if `desired the illustration may be inthe forni of a moving picture, or a photograph. The

observers obtain a. close-up view of this picked cotton `and can see hovv it differs from the baled cotton. After th-e observers -have been given sufficient timeto observe this picked cotton and the pickers and read the legend, another lug in the chain' 23 comes into position to engage another one of the pins 3l and start turning the sceneshifter to-position to .conceal 4the picked cotton. At the sametim'e'that the first turntableis being 'turned to the concealing' `position, the second turntablev is being turned to the displaying position so as to show a sample of the carded cotton, and,` When the movement of this turntable has been completed, the lamp 85 is lighted and noiv the observer sees, in addition to the carded cotton, a legend describing what is being` shown and illustrations of an appropriate machine used for cai'ding cotton.

. The succeeding turntables and transparencies are brought to the observer-s attention one after. the other .until the cotton cloth is 'shown as having been bleached. ii'iechaiiisni for driving the cai' -71.is now moved around to a. position'so as to bring this car out of the opening 72 and carry .it around inside the opening 73.

lt has been found that tli-e device has been very satisfactory for making demonsti-ations in show Windows. lt can then standing outside the window.

His attention is concentrated upon thedisplay being put out by the device.j Fui'ther-- more, the device operates under ideal lightiiigconditions, as Yit is adapted to operate iii daylight' or at night in an illuminated store Window.
